Two NIEHS/NTP scientists and two NTP postdoctoral fellows recently took an important step along toxicology's professional track, by satisfying requirements for Diplomate of the American Board of Toxicology (DABT) certification. DABT certification often offers an advantage in the job market and career advancement, and has been associated with higher levels of compensation.

The American Board of Toxicology (http://www.abtox.org/ABOT_about.shtml)  was established in 1979 to advance standards in the field of toxicology and confer recognition upon those members of the profession who, measured against such standards, demonstrate competence. Certification requirements include a combination of education and experience and a three-part examination.

Several toxicologists at NIEHS/NTP have qualified for the coveted DABT, among them NIEHS/NTP Director Linda Birnbaum, Ph.D., who is the first toxicologist to head the Institute. Birnbaum offered the new diplomates her sincere congratulations. “Welcome to the club!” she wrote. “This marks a very important milestone in your careers.”

New holders of the DABT are:

• Danielle Carlin, Ph.D., a health scientist administrator with the NIEHS Superfund Research Program, who joined the NIEHS Division of Extramural Research and Training in 2010, after completing a postdoctoral fellowship at the U.S. Environmental Protection Agency

Xiaoqing Chang, Ph.D., a visiting fellow in the NTP Biomolecular Screening Branch headed by Raymond Tice, Ph.D., mentored by Michael DeVito, Ph.D., leader of the Experimental Toxicology Group in the NTP Toxicology Branch

• Minerva Mercado-Feliciano, Ph.D., an Intramural Research Training Award fellow in the NTP Toxicology Branch headed by Paul Foster, Ph.D.

Cynthia Rider, Ph.D., a toxicologist in the NTP General Toxicology Group who joined NIEHS/NTP in 2010, after completing postdoctoral work at Duke University and the U.S. Environmental Protection Agency

Diplomates hold initial DABT certification for 5 years and must demonstrate that they actively practice toxicology, engage in continuing education, and maintain expert knowledge in their field prior to receiving recertification.
